1.2THEFLUID
GMV use and recommend an hydraulicfluid ISOVG46 that :
·Thanksto classification ascategoryHEES, asrule ISO-UNI 6743-4 and
itsbiodegradabilityindex>90%, according to standard CEC L33-A-
93, isacceptable froman environmentalpoint ofview.
·Thanksto the syntheticbase (ISOVG46 )and itsviscosityindex
(>140), higherthan the traditionalmineraloil, allowing greaterstability,
ensuring betterperformance against wearand aging on systemsas
liftsforpersonsand goods, in accordance with the environmental
directive 2006/118/EC.
·Thanksto a flash point above 220°C compared to the 140°C ofthe
traditionalmineraloil it issaferand reducesthe riskoffire.

1.3HOWTHENGVA3WORKS
The valve NGVismade with a non-return valve VR, a controlspoolVB controlled bya stepping motorand by
a systemwith pilot operated non-return valve VRP-P
(moved in opening bythe electro-valve VMD)
Valve VR It isa valve that prevent , during the downward, the oil inlet to the pump.
It forcesthe oil that comesfromthe VRPC2 to pass through the spoolVB and then in the
C3 and in the tankT1.
Valve VRP-P It isthe pilot operated non-return valve, requested byrules.
During upward the valve worksonlyasON/OFF, the spoolVRPopensorcloses
depending on the oil that comes. Itsposition isdetermined bythe ratio between the
pressure that developsin the chamberC2 and the one that occurs in chamberC1
During downward, instead, it opensthe oil wayto the valve block(chamberC2).
Itsopening ismade bythe pushing ofthe piston Pthat isopened bythe pilot operated
valve VMD
Spool VB It’sthe main part ofthe controlblock.
It adjuststhe oil quantitythat should be discharged and determinesall the movementsof
the car
Itsmovement iscontrolled bya stepping motorcoupled to the spoolVB, through a screw-
nut coupling (necessaryto transformthe rotatorymotion into translatory).
The spooladjustsboth the upward phase (with a direct controlofthe oil that should be
discharged and, indirectlythe oil forthe cylinder) than that ofdownward (directly)

1.4THEDOUBLESAFETY
Forthe double safetythe systemhastwo spoolsin series, the VRPand the VB.
Both worktogetherto stop the carin different waysbetween upvward and downward
UPWARD
The spoolVB controlsacceleration and deceleration.
During the approach to the landing, the spoolVB, will be almost fullyopen to discharge a quantityofoil
equalto:
Qt =Qp -Qc
where
Qt =Oil sent to the drain through the VB, Qp=Pump flow
Qc=Flowto the cylinder, corresponding to the carspeed
The carstop at the landing ismade byopening completelythe VB and bringing the value ofQt =Qp. Asa
result Qc becomeszero.
The carstopswhen the pressure ofthe chamberC2 become equalto the pressure ofthe chamberC1
(Staticpressure ofthe system). In thiscase,
the VRPspoolcloses, because ispushed bythe pressure and
bythe spring, and the carstopsat the landing.
DOWNWARD
The downward phase issimplerand, afterthe opening ofthe VRPspool, the carspeed iscontrolled bythe
VB spool. To a more opening ofthe spoolcorrespondsan higherspeed ofthe car
The phase ofarrivalat the landing isdetermined bythe following events:
The VRPspoolisopened bythe push ofthe spoolsP, controlled bythe VMD pilot valve
The VB spoolclosesto stop the car
The VMD valve, raised the landing, isde-energized and consequentlythe VRPspoolcloses.
During standard operation ofthe system, both upward and downward, the properworking ofthe two
spools(VRPand VB)acting in series, iscontrolled bythree switches:
One, (S1)installed on the VRP, to controlthe full close position.
Two (S2, S3)installed on the VB, to controlthe full close and the full open positions
During all phasesthe systemcontrolthat the spoolsreach the correct open and close position.
Ifthisdo not happen, the systemsend an alarmto the controlpanel, which must turn the systeminto the
out ofservice status
WARNING
Needfulprerequisite ofthe controlpanel, when the systemisoutside ofthe doors unlocking zone, is
that it doesnot send commandsto the card and/orthe motor/ pump.

The contemporaryofthe ON orOFF statusrequire different behaviours, in particular:
IfRDYand RUN are both in ON status, the controlpanelmust detect the error, move the carto the nearest

2.8.1CONNECTION WITH FLEXIBLE HOSE
·Remove the gearand the cutting ring fromthe terminal
connection ofthe silencer.
·Ensure that the terminalconnection iswell fixed on the
silencer.
·Clean and oil the threading and theirseats.
·Fixthe flexible hose verifying it isthoroughlytightened.
WARNING
Ensure that there isno dirtyinside the tube. These
impuritiescould damage the sealing ofthe piston and of
the valve blockand inhibit the correct operation ofthe
system.
2.8.2CONNECTION WITH A RIGIDPIPE
·Cut at 90°the head ofthe tube with a saw(do not use a tube-cutter)
·Do not let metalresidualsfall into the tube and eliminate the burrs internallyand externally.
·Remove the gearand the cutting ring ofthe terminalconnection and insert it on the pipe.
·Ensure that the cutting ring isinserted asindicated in image
·Ensure that the terminalconnection iswell fixed on the silencer.
·Clean and lubricate the threading and the connection seat with
a slight oil veil.
·Insert the pipe into the cone at 24°up to layit on the stop limit
ofthe cone itself.
·Screwthoroughlythe gearbyhand until it isfelt that the cutting
gearlaysperfectlyto the nut.
·Then screwthe nut using a wrench until the cutting edge ofthe
ring isin contact with the tube and preventsit fromrotating.
·Keep the tube against itsstop to avoid it rotates, screwthe
fixing nut by3/4 rev. In doing so the ring engraveswith the
necessarydepth the externalpart ofthe tube and risesa
borderin front ofitscutting edge.
·Loose the nut and checkthat the tube hasall around a well
risen border. The bordermust cover70%ofthe front part of
the cutting ring.
·Fixthe tube, close the nut with a wrench until a certain
resistance isfelt; fromthismoment on screwfora further1/4
turn, contrasting wrench against wrench.
WARNING
Ensure that there isno dirtyinside the tube. These impuritiescould damage the sealing ofthe piston
and ofthe valve blockand inhibit the correct operation ofthe plant.

3.3CONNECTIONS
3.3.1CONTROLPANEL INTERFACE
The input circuitsare divided in two groups, both isolated fromthe card powersupply:
· V0,V1,V2,VS with common V- · D+with common D-
Each group can be powered orbyan externalsource within established limits, ordirectlybythe card power,
connecting the commons(V-and/orD-) to the A-.
The interfacing with the controlpanelismade via removable terminalconnectors defined asfollows:
